I have always wanted to go out on my own and try consulting. When I look at the cost of health insurance for my family, it makes me reconsider every time.
Is there an affordable way to get health insurance for an independent consultant.
Any insight from others on this forum is greatly...
I am working on an MDMT determination for a vessel that has PWHT because it is in caustic service. PWHT is not otherwise required.
If a vessel has PWHT for service, do I get to take the 30 deg reduction in MDMT that is allowed by paragraph UCS-68(c).
I am having trouble determining exactly...
I am using a Nickel Anti-Seize thread lubricant on the studs of a flanged joint. I am trying to calculate the target torque to achieve the desired bolt stress. I am having trouble determining the proper coefficient of friction to use in the formula. The product data sheet for the particlar...
I am trying to use Fig UCS-66 for a nozzle neck constructed of SA-333 Gr.3 material. The shell of the vessel is constructed of SA-203 Gr. E material.
In the notes section, SA-333 material is not assigned to any curve. I assume that it would have the same requirements as the SA-203 Gr. E since...
Does anyone know the reason why vessels that were built to the 1968 or previous editions of the pressure vessel code cannot be re-rated using the current code?
I am having some nozzles added to a vessel. As a part of the specification for the alteration, it states that materials from Eastern Europe or Russia need to be approved on an individual basis.
The vessel fabricator has manufactured some of the nozzles using SA106 GrB material from a Ukrainian...
I am adding (3) 1-1/2 nozzles to a 20" 300# manway cover for use as termowell connections.
My nozzles meet the requirements of UG-36(c)(3)for not needing re-inforcement. When I do an appendix 2 calculation for the flange thickness, the required thickness is greater than the 2-9/16" thickness...
I am considering starting a consulting business in Texas. I would be the only employee at the start.
Does anyone know of some good references concerning starting an engineering consulting business.
I am looking for information on the legal aspects of setting up a consulting business with...
I have a European material designated as 45CrMoV4. I am trying to find out what it is so that I can get an equivalent AISI material. Does anyone know where I can find a reference that would tell me the chemistry of European materials and their AISI equivalents.
We have a situation where we are welding a Long Weld Neck flange to a condensate drum while the drum is in service so that a hot-tap can be performed. We would like to minimize the amount of welding.
Is it acceptable to use less than a full penetration weld if all of the strength path...
We have a line on our Demethanizer that has several breeches in the insulation jacket. Ice is visible at the breeches.
My worry is that a large amount of ice has accumulated inside the insulation underneath the jacket and is not visible. Since the line is sch 10S, there is not any extra wall...
I am looking for a training program to learn welding engineering. I already have an engineering degree, but I am looking for an in-depth course where I can learn welding engineering from a distance. (ie. a correspondence corse)I have been asked by my company to become the onsite welding expert...
I am trying to calculate a torque for bolts on a B16.5 flange. When I use the section VIII appendix 2 calculation for flange stress, I can only put a small stress on the bolts (about 25% of yield). Beyond this load the flange is overstressed due to gasket seating stresses.
We routinely torque...
I am looking for some advice on guiding a vertical cold insulated line that is guided from a vessel. The existing guide has a 2" gap all around and is guided from the OD of the insulation. There is a sleeve on the insulation.
My problem is that the line has two-phase flow and vibrates...
I have a question about transitioning from HDPE pipe to steel pipe. I have seen specifications that call for the transition to be above ground and other specifications that call for the transition to be below ground. If any of you have any insights as to why one method would be used over the...
I'm looking for advice on techniques to measure the amount of creep that has been sustained by furnace tubes.
Also, what is considered an acceptable amount of creep?
Are there any codes or standards that provide guidelines?
